Are You Sitting Comfortably? Users’Perceptions of a Pelvic Tilt Chair

Abstract

An evaluation of a “Pelvic Tilt Chair’’ is described. Twenty one volunteers were given
a prototype chair to use in their own offices for a period of 1 month. Ergonomic and anthropometric data and data concerning the subjects’ history of back pain and occupational sitting' behaviour were obtained. The subjects were characterised as a heterogenous group of chronic low back sufferers. Subjective data concerning back pain, acceptability, comfort and preference demonstrated that a large percentage of the subjects reacted positively to the prototype chair. Future research directions are outlined on the basis of this. It is argued that the concept merits further attention from those concerned with the treatment and pre-vention of low back problems.
